I suspect this is part of covering their ass for GDPR. Pose everything as a security problem, so you can claim you have legit interest in tracking all of that.

> How difficult would it be for a bot to simulate a human's mouse movements?

Simulating? Extremely difficult. Perturbing pre-recorded paths is a bit easier to do, but requires pre-recording of a lot of paths. One of the fastest ways to get your Poker bot banned is to not fix this one way or the other.

> Also, doesn't this conflict with rare types of input devices? Or people with a motor function disability?

It still tracks the mouse movements, just now being able to classify their users as disabled or using an arcane device (both of which are interesting tidbits to add to your advertisement profile).
